Massive improvement over the "Bonk Demons" predecessor. However, there's some baffling design choices here. Namely, controls in the skill tree are sluggish and could easily be enhanced by allowing scrolling in/out, and dragging the screen to pan across the skill tree.
The gameplay itself is much better here, but still leaves a lot to be desired. The biggest issue is the hit detection of your swings, and the inability to control which direction you're swinging. Intuitively, it'd make sense that if you're clicking to the right of your character that you'll swing in that direction. Instead, it's hard to figure out what actually dictates the direction of your swing, leaving you smacking the ground while standing right beside a mob of enemies.
It's a step in the right direction. The balancing is still confusing as you can afford around a dozen upgrades after your first round, but then you'll need to run through several more rounds just to afford a single upgrade shortly thereafter. Feels like a throwaway project, and definitely still not something anyone should play. There's a fun game in there if it can be fixed up.
